An electric heater is an electrical device that converts an electric current into heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy.
How does an electric house heater work?
Electric furnaces act much like a hair dryer. They pull air into the system and through a heat exchanger. Once in the heat exchanger, electric heating elements will warm up the air. This warm air is then pushed by the blower into the ductwork in your home, which distributes the air into the rooms of your home.

How bad is electric heat?
Electric heating is less efficient. Electric heating takes more energy to heat the air circulating throughout your home. Electric heating is also “less clean” than gas heating. Ultimately, burning coal is this furnace’s main source of electrical power, which is worse for the environment than natural gas.
What does Electric Heat look like?
Q: How do I know if my heater is electric or gas? A: In order to tell if your heating system is electric or gas, check the front of your heating unit.

How do electric heaters cause fires?
Glenn Corbett, an associate professor of fire safety and public management at John Jay College, said that space heaters typically cause fires when they malfunction. This can be caused by overheating because they were left on too long, and older models may not have newer safety features such as an automatic shut-off.
Why do radiators go under Windows?
In the past, radiators have often been located under the window in a room because this is the coldest area in the room. This interacts with the cold air from the window, and this cold air then helps push the hot air from the radiator into the room.
Does a heater use heat energy?
A warm-air heating system uses thermal energy to heat air and then forces the warm air through a system of ducts and registers.
